We sent the first humans to land on the Moon in 1969. Since then, only of 12 men have stepped foot on the lunar surface – but we left robotic explorers behind to continue gathering science data. And now, we’re preparing to return. Establishing a sustained presence on and near the Moon will help us learn to live off of our home planet and prepare for travel to Mars.
To help establish ourselves on and near the Moon, we are working with a few select American companies. We will buy space on commercial robotic landers, along with other customers, to deliver our payloads to the lunar surface. We’re even developing lunar instruments and tools that will fly on missions as early as 2019!
Through partnerships with American companies, we are leading a flexible and sustainable approach to deep space missions. These early commercial delivery missions will also help inform new space systems we build to send humans to the Moon in the next decade. Involving American companies and stimulating the space market with these new opportunities to send science instruments and new technologies to deep space will be similar to how we use companies like Northrop Grumman and SpaceX to send cargo to the International Space Station now. These selected companies will provide a rocket and cargo space on their robotic landers for us (and others!) to send science and technology to our nearest neighbor.
So who are these companies that will get to ferry science instruments and new technologies to the Moon?
Here’s a digital “catalogue” of the organizations and their spacecraft that will be available for lunar services over the next decade:
Pittsburg, PA
Littleton, CO
Cedar Park, TX
Houston, TX
Littleton, CO
Mojave, CA
Cape Canaveral, FL
Edison, NJ
Cambridge, MA
We are thrilled to be working with these companies to enable us to investigate the Moon in new ways. In order to expand humanity’s presence beyond Earth, we need to return to the Moon before we go to Mars.
The Moon helps us to learn how to live and work on another planetary body while being only three days away from home – instead of several months. The Moon also holds enormous potential for testing new technologies, like prospecting for water ice and turning it into drinking water, oxygen and rocket fuel. Plus, there’s so much science to be done!
The Moon can help us understand the early history of the solar system, how planets migrated to their current formation and much more. Understanding how the Earth-Moon system formed is difficult because those ancient rocks no longer exist here on Earth. They have been recycled by plate tectonics, but the Moon still has rocks that date back to the time of its formation! It’s like traveling to a cosmic time machine!
Join us on this exciting journey as we expand humanity’s presence beyond Earth.

Satellites are crucial to everyday life and cost hundreds of millions of dollars to manufacture and launch. Currently, they are simply decommissioned when they run out of fuel. There is a better way, and it centers on satellite servicing, which can make spaceflight more sustainable, affordable, and resilient. Our satellite servicing technologies will open up a new world where fleet managers can call on robotic mechanics to diagnose, maintain and extend the lifespan of their assets.
Our new and unique robot is designed to test robotic satellite servicing capabilities. Standing 10 feet tall and 16 feet wide, the six-legged “hexapod” robot helps engineers perfect technologies before they’re put to use in space.
Here are SIX interesting facts about the hexapod:
This essentially means the robot can move in six directions—three translational directions (forward and backward, up and down and left and right), and three rotational directions (roll, pitch and yaw). Because of its wide range of movement, the hexapod mimics the way a satellite moves in zero gravity.
Like most space simulators, the hexapod typically moves slowly at about one inch per second. During tests, it remains positioned about nine feet off the floor to line up with and interact with a robotic servicing arm mounted to an arch nearby. However, the robot can move at speeds up to eight inches per second and extend/reach nearly 13 feet high!
The hexapod is crucial to testing for our Restore-L project, which will prove a combination of technologies needed to robotically refuel a satellite not originally designed to be refueled in space.
Perhaps the most difficult part of refueling a satellite in space is the autonomous rendezvous and grapple stage. A satellite in need of fuel might be moving 16,500 miles per hour in the darkness of space. A servicer satellite will need to match its speed and approach the client satellite, then grab it. This nail-biting stage needs to be done autonomously by the spacecraft’s systems (no humans controlling operations from the ground).
The hexapod helps us practice this never-before-attempted feat in space-like conditions. Eventually a suite of satellite servicing capabilities could be incorporated in other missions.
Because of the hexapod’s unparalleled* ability to handle a high load capacity and range of movement, while maintaining a high degree of precision and repeatability, a similar kind of robot is used for flight and roller coaster simulators.
*Pun intended: the hexapod is what is referred to as a parallel motion robot
The hexapod was designed and built by a small, New Hampshire-based company called Mikrolar. Mikrolar designs and produces custom robots that offer a wide range of motion and high degree of precision, for a wide variety of applications.
The hexapod conducts crucial tests at our Goddard Space Flight Center’s Robotic Operations Center (ROC). The ROC is a 5,000-square-foot facility with 50 feet high ceilings. It acts as an incubator for satellite servicing technologies. Within its black curtain-lined walls, space systems, components and tasks are put to the test in simulated environments, refined and finally declared ready for action in orbit.
The hexapod is not alone in the ROC. Five other robots test satellite servicing capabilities. Engineers use these robots to practice robotic repairs on satellites rendezvousing with objects in space.

Currently, six humans are living and working on the International Space Station, which orbits 250 miles above our planet at 17,500mph. Below you will find a real journal entry, written in space, by NASA astronaut Scott Tingle.

Wow, time has gone by extremely fast. The mid-deployment phase will be short-lived for me this time, as the new crew (Drew Feustel, Ricky Arnold, and Oleg Artemyev) will arrive on March 23rd, and then we have at least one spacewalk on the 29th, followed by a planned SpaceX Dragon cargo craft arrival on the 4th of April. It’s a little strange being up here with only two other crewmates. We are still very busy, but the overall work effort is half of what it was just a week ago. My crewmate, Nemo (Norishige Kanai), and I are trying to use the time to prepare for the upcoming very busy schedule, and we have been having some great success getting a ton of details taken care of.
Yesterday I had a funny event, though. I was controlling a robot named “Justin” who was located in Munich. The research and demonstration events were so interesting and fun that I offered them my lunch hour to do an additional protocol and have a longer debrief session. The ground team responded happily and accepted the offer – any extra time with crew onboard the International Space Station (ISS) is valuable to our programs. Halfway through the event, the team needed a few minutes to shut down and restart the robot, and I surmised that since I was skipping my break, this would be a good time to use the toilet. And I did, use the toilet. And literally 3 minutes later I returned, waited another 2 minutes for the robot systems to connect, and we began another great session controlling Justin from ISS with no loss to science.
Later that same day, I was approached by the ground team in Houston (not the test team I was working with in Munich) and queried if something was wrong, and why did I have to take a toilet break while we were executing valuable science? They were concerned that I might have a medical issue, as taking a break in the middle of some very valuable science is not normal for us to do while on ISS. It’s nice to know that we have literally hundreds of highly-trained professionals looking out for us.

How many connections does America’s space program have with the fictional world of Star Wars? More than you might think…
Join us as we highlight a few of the real-world TIE-ins between us and Star Wars:
Lasers in space sounds like something straight out of Star Wars, but it’s also a reality for us. Our own GEDI (yes, like Jedi) instrument will launch later this year to the International Space Station.
GEDI stands for the Global Ecosystem Dynamics Investigation lidar. It will study the height of trees and forests, using three lasers split into eight tracks, and create a 3D map of forests around the planet.
With GEDI’s new tree maps, we’ll get a better understanding of how much carbon is stored in forests all over Earth, and how forests will be able to absorb increasing carbon dioxide in the atmosphere.
The Jedi knights may help protect a galaxy far, far away, but our GEDI will help us study and understand forest changes right here on Earth.
There’s another Jedi in town and it happens to be orbiting the planet Jupiter. Our Juno spacecraft, which arrived at the gas giant in July 2016, has an instrument on board that goes by the name of JEDI - the Jupiter Energetic Particle Detector Instrument.
While it doesn’t use a light saber or channel “the force”, it does measure high-energy particles near Jupiter. Data collected with the JEDI instrument will help us understand how the energy of Jupiter’s rotation is being funneled into its atmosphere and magnetosphere.
We know what you’re thinking...”That’s no moon.” But actually, it is! This is a real picture taken by our Cassini spacecraft of Saturn’s moon Mimas. In this view taken on Cassini’s closest-ever flyby of Mimas, the large Herschel Crater dominates, making the moon look like the Death Star. Herschel Crater is 130 kilometers, or 80 miles, wide and covers most of the right of this image.
We have robots roving and exploring all over the solar system, but it's our own “R2” that's most likely to resonate with Star Wars fans. Robonaut 2, launched in 2011, is working along side humans on board the International Space Station, and may eventually help with spacewalks too dangerous for humans. Incidentally, an earlier version of Robonaut bore a strong “facial” resemblance to enigmatic bounty hunter Boba Fett.
Another "droid" seen on the space station was directly inspired by the saga. In 1999, then Massachusetts Institute of Technology (MIT) professor David Miller, showed the original 1977 Star Wars to his students on their first day of class. After the scene where hero Luke Skywalker learns lightsaber skills by sparring with a floating droid “remotes” on the Millennium Falcon, Miller stood up and pointed: "I want you to build me some of those."
The result was "SPHERES," or Synchronized Position Hold, Engage, Reorient, Experimental Satellites. Originally designed to test spacecraft rendezvous and docking maneuvers, the bowling-ball size mini-satellites can now be powered by smart phones.
When space shuttle Atlantis left the International Space Station after 2007’s STS-117 mission, it caught a view of the station that looked to some like a TIE fighter.
The "TIE-ins" go beyond casual resemblance to real engineering. We already use actual ion engines ("TIE" stands for "Twin Ion Engines") on spacecraft like Dawn, currently orbiting the dwarf planet Ceres. In fact, Dawn goes one better with three ion engines.

Water is a precious resource -- especially on the Moon! In the near future, robotic rovers may roam the Moon’s poles in search of hidden reservoirs of water beneath the lunar surface. But traversing the poles can be a perilous journey. Depending on the Sun’s position in the sky and the way that its light falls on the surface, hazards such as boulders and craters can be difficult, if not impossible, to see.
Inside our Lunar Lab at Ames Research Center, researchers are using Hollywood light kits and a giant sandbox filled with 8 tons of artificial Moon dirt to simulate driving conditions at the poles. The research aims to provide rovers and their human supervisors with 3-D hazard maps of the Moon’s terrain, helping them to avoid potential obstacles that lie ahead.
Researchers begin with a map of the Moon’s terrain that’s randomly generated by a computer. Each scene is based on observations made from lunar orbit. The map indicates the number, location and size of features like rocks and craters that should be placed inside the 12x12-foot testbed.
Using the map as a guide, researchers build the terrain by hand with everyday tools. The terrain is then dusted with a top layer of artificial Moon dirt to eliminate shovel and brush marks.
Lights are positioned at different locations around the testbed. One by one, the lights are switched on and off while a camera captures images of the terrain. Notice how the appearance of the terrain changes depending on the source of illumination.
Using a computer algorithm, a 3-D hazard detection model of the terrain is generated from the images. The model provides important information about the size of an obstacle, its height and where it’s located.
With this technique, researchers can teach a rover to recognize the effect of different lighting conditions on the Moon’s poles. The tool could come in handy for future lunar rover missions like Resource Prospector, which will use a drill to search for subsurface water and other compounds on the Moon.

Meet Robonaut, our humanoid robot (which means it’s built to look like a person). This makes it easier for Robonaut to do the same jobs as a person.
Robonaut could help with anything from working on the International Space Station to exploring other worlds…and now he might even take up a job as a referee!
But it’s not all fun and games for Robonaut...from performing movements like a referee to helping astronauts on the space station, it’s important to have a robot that can perform the same tasks as humans. Why?
Robonaut could someday be tested outside the space station. This testing would determine how well Robonaut could work with, or instead of, spacewalking astronauts. Designers even have ideas for sending a robot like Robonaut to another world someday. If testing goes well, who knows where Robonaut - or a better robot based on Robonaut - could end up?

It’s been a long, technical journey for the seven teams competing this week in Level 2 of our Sample Return Robot Challenge. Over the past five years, more than 50 teams have attempted the $1.5 million competition, which is looking to develop autonomous capabilities in robotics. Basically, we want robots that can think and act on their own, so they can travel to far off places – like Mars – and we can rely on them to work on their own when a time delay or unknown conditions could be factors.
This challenge has two levels, both requiring robots to navigate without human control and Earth-based tools (like GPS or magnetic compassing). The robot has to find samples, pick them up and deliver them to home base. Each of the final seven teams succeeded at Level 1, where they had to find one sample, during previous competition years. Now, they have a shot at the much more difficult Level 2, where they have a two-hour window to locate up to 10 samples of varying point values, but they don’t know where to look or what exactly they’re looking for.
Get to know the final seven, and be sure to cheer them on as we live-stream the competition all day Sept. 4 and 5.
West Virginia University Mountaineers Hailing from: Morgantown, West Virginia # of Team Members: 12
Behind the Name: In West Virginia, we call ourselves mountaineers. We like to explore unknown places and be inspired by nature.
Motivation: To challenge ourselves. Through this venture, we are also hoping to create research and career opportunities for everyone on the team.
Strategy: Keeping things simple. Through participating in SRR challenge during the last three years, we have gone a long way in streamlining our system.
Obstacles: One of the biggest challenges was finding and nurturing the talent of individual team members and coordinating the team in making real progress on time.
Prize Plans: We donated 50 percent of our 2015 Level 2 prize money to create an undergraduate “Robotics Achievement Fellowship” at WVU. The rest of the funding was allocated to support team member professional development, such as traveling to conferences. A similar model will be used if we win in 2016.
Extra Credit: We did an Easter egg hunt with our robot, Cataglyphis (named after a desert ant with extraordinary navigation capabilities), last year.
Survey Hailing from: Los Angeles, California # of Team Members: Jascha Little
Behind the Name: It's short, simple, and what the robot spends a lot of its time doing.
Team History: We work together, and we all thought the challenge sounded like an excellent way to solve the problem of what to do with all our free time.
Motivation: We are all engineers and software developers that already work on robotics projects. Reading too much sci-fi when we were kids probably got us to this point.
Strategy: We are trying to solve the search-and-return problem primarily with computer vision. This is mostly to reduce cost. Our budget can't handle high quality IMUs or LIDAR.
Prize Plans: Probably build more robots.
Extra Credit: Favorite pop culture robot is Bender (Futurama). Alcoholic robots are the best.
Alabama Astrobotics (The University of Alabama) Hailing from: Tuscaloosa, Alabama # of Team Members: 33
Behind the Name: “Alabama Astrobotics” was chosen to reflect our school affiliation and our mission to design robotics for various space applications.
Team History: Alabama Astrobotics has been involved with other NASA robotics competitions in the past. So, the team is accustomed to the competition environment.
Motivation: We are pleased to have advanced to Level 2 in our first year in the competition (the first team to do so), but we are also not satisfied with just advancing. Our goal is to try to solve Level 2.
Strategy: Our strategy is similar to that used in Level 1. Our Level 1 approach was chosen so that it would translate to Level 2 as well, thus requiring fewer customizations from Level 1 to Level 2.
Obstacles: As a university team, the biggest challenge was not having all our team members available to work on the robot during the time since Level 1 completed in June. Most of my team members have either graduated or have summer internships, which took them away from campus after Level 1. Thus, we didn’t have the manpower to address the additional Level 2 technical challenges.
Prize Plans: Any prize money would be donated to the University of Alabama College of Engineering.
Extra Credit: Alabama Astrobotics also competes in the annual NASA Robotic Mining Competition held at the Kennedy Space Center each May. We have been fortunate enough to win that competition three times in its seven year history, and we are the only team to win it more than once.
MAXed-Out Hailing From: Santa Clara, California # of Team Members: 4
Behind the Name: Several reasons: Team leader is Greg Maxwell, and his school nick name was Max. Our robot’s name is Max, which is one of the most common name for a dog, and it is a retriever. Our efforts on this has been too the max…. i.e. MAXed-Out. Our technology requirements have been pushed to their limits - Maxed-Out.
Team History: Greg Maxwell started a Meet-up “Silicon-Valley Robot Operating System” SV-ROS that was to help teach hobbyists how to use ROS on their robots. We needed a project to help implement and make real what we were teaching. This is the third contest we have participated in.
Motivation: There is still such a long way to go to make robots practical. Every little bit we can contribute makes them a little bit better and smarter. Strategy: Level 1 was a test, as a minimum viable product to prove the tech worked. For Level 2, we had to test and add obstacle avoidance to be able to cover the larger area with trees and slopes, plus add internal guidance to allow for Max to be out of the home base camera tracking system.
Obstacles: Lack of a cost effective robot platform that met all the requirements; we had to build our own. Also time and money. The two months (between Level 1 and 2) went really fast, and we had to abandon lots of cool ideas and focus on the basics.
Prize Plans: Not sure, but pay off the credit cards comes to mind. We might open-source the platform since it works pretty well. Or we will see if it works as expected. We may also take a break / vacation away from robots for a while.
Extra Credit: My nephew, Max Hieges, did our logo, based on the 1960-era Rat Fink sticker.
Mind & Iron Hailing From: Seattle, Washington # of Team Members: 5
Behind the Name: It was the original title for Isaac Asimov’s “I Robot,” and we thought it was a good combination of what a robot actually is – mechanical and brains.
Team History: Three of us were WPI undergrads and met at school; two of us did our master’s degrees at the University of Washington, where we met another member, and then another of us brought on a family member.
Motivation: We saw that there was an opportunity to compete in a challenge that seemed like there was a reasonable solution that we could tackle with a limited budget. We saw three years of competition and thought that we had some better ideas and a pretty good shot at it. Strategy: The samples and the terrain are much more complex in Level 2, and we have to be more careful about our navigation. We are using the same tools, just expanding their capability and scope.
Obstacles: The team being spread over three different time zones has been the biggest challenge. We are all doing this in our free time after work. The internet has been really handy to get things done.
Prize Plans: Probably invest in more robot stuff! And look for other cool projects we can work on, whether it’s another NASA challenge or other projects.
Extra Credit: We are hoping to collaborate with NASA on the professional side with surgical robots to exoskeletons. Challenge-related, our robot is mostly made of plywood – it is a composite fiber material that works well for fast development using cheap materials.
Sirius Hailing From: South Hadley, Massachusetts # of Team Members: 4
Team History: We are a family. Our kids are both robot builders who work for Boston Dynamics, and they have a lot of robot expertise. Both of our kids are robotics engineers, and my wife is intrinsically brilliant, so the combination of that makes for a good team.
Motivation: Because it’s a really hard challenge. It’s one thing to drive a robot with a remote control; it’s another to do the whole thing autonomously. If you make a single change in a robot, it could throw everything off. You have to think through every step for the robot. On a basic level, to learn more about robotics and to win the prize. Strategy: Very similar to Level 1. We approached Level 1 knowing Level 2 was there, so our strategy was no different.
Obstacles: It is very difficult to do object recognition under unpredictable conditions – sun, clouds, weather, sample location. The biggest challenge was trying to recognize known and unknown objects under such a wide variety of environmental possibilities. And the terrain is very different – you don’t know what you’re going to find out there.
Prize Plans: We haven’t really thought about it, but we will give some away, and we’ll invest the rest in our robotics company.
Extra Credit: The first robot we had was called Robo-Dad. Dan was training to be an astronaut in the 1990s, so we built a toy remote-controlled truck that Dan - in Texas - could control via the internet in the house. Robo-Dad had a camera that Dan could see the house with. It had two-way communication; it was a little before it’s time – the internet was very slow.
Team AL Hailing From: Ontario, Canada # of Team Members: 1
Team History: I was looking for competitions that were open, and my dad had followed the Centennial Challenges for a while, so he alerted me to this one. I was already doing rover projects, and it was appropriate and awesome and interesting. I felt like I could do it as a team of one.
Motivation: Difficult challenges. I’m definitely inspired seeing really cool robots that other people are building. New emerging tech really motives me to create new things.
Strategy: I showed up with another robot to Level 2. I built three, but ran with only two. It did make it more complicated, but the strategy was to send them to different areas and have them be able to communicate with each other. Everything physically was the same from Level 1. The idea is that they would all go out with different missions and I would maximize field coverage.
Obstacles: Time. More time would always be nice. Being able to make something like this happen under a timeline is really difficult. I feel like I accomplished a lot for a year. Also, manpower – being a team of 1, I have to do all of the paperwork and other related stuff, but also carry the hardware and do the programming. You have to multitask a lot.
Prize Plans: I’d like to start a robotics company, and be able to expand some of the things I’ve been working on associated with technology and maker education.
Extra Credit: My story is not linear. A lot of people are surprised to hear that my background is in molecular biology and research. I once lived in a tent in Madagascar for a few months to do a biodiversity study, and I have multiple publications from that side of my life. I am in a whole different place now.
The competition is one of many run by our Centennial Challenges program, which looks to the public – citizen inventors, academics, makers, artists, YOU – to help us advance technology and bring a different perspective to obstacles that gets us outside of our traditional solving community. See what else we’re working on here.

Our InSight mission will place a fixed science outpost on Mars to study its deep interior. Findings and research from this project will address one of the most fundamental questions we have about planetary and solar system science – How in the world did these rocky planets form?
By investigating the interior structure and processes of Mars, the InSight mission will gain a better understanding of the evolutionary formation of planets, including Earth.
InSight will record Mars’ vital signs to learn more about the planet, including:
Seismic Activity:
A seismometer will be used to record the seismic activity on Mars. This will give us information on the crust, mantel and core; and the relationship between them.
Temperature:
A heat flow probe will be used to take Mars’ temperature and determine the change over the course of a full Martian year.
Reflexes:
By looking at how the rotation of Mars wobbles, we will better understand what the core size may be and its composition.
Launch for the InSight mission is scheduled for March 2016, and even though you can’t physically travel with the lander, you can send your name to the Red Planet onboard. Make sure to submit your name before Sept. 8!
